T @ZZ HUM/"mf 777/002/ @0N/06TH: of performing a piece of music. 4designates Be it known thatI, GEORGE B.

In the manner and by the substantial ldesignates a tracker-board; 2, a music-roll means referred to the sheetof music-paper that is to say, the roll upon which the sheet as itpasses from the music-roll onto the take- 3 of perforated music isinitially wound and up roll over the tracker-board is guided in its uponwhich it is introduced into the instrupassage over the latter, so thatthe perforament and from which it is unwound in the act tions thereofWill register accurately with the ducts in said tracker-board, and bymanipulation of the adjusting-rod the guides may be adjusted to and fromeach other to compensate for variations due to climatic changes orotherwise in the width of music-sheets.

In order to provide for imparting the proper tension to the music-sheet,so that it may be maintained in a smooth or taut condition withoutwrinkles and held down into close coperative contact with thetracker-board in its passage thereover, tension-rollers 11 12 areprovided. These rollers are journaled in suitable journal-standards 13in such manner that they will rotate in contact with the music-sheet andimpart tension to the latter. As shown, one of the tension rollers, 11,is passed through openings therefor in the guides so that the latter maybe adjusted to and from each other along said roller. The othertension-roller, 12, is arranged to be removable and replaceable withconvenience to facilitate proper establishment of the music-sheet inoperative connection with the other elements -in the instrument,avoiding the tedious operation of threading the same in between thetension-rollers. This is accomplished by mounting' the tension-roller 12at one end in a journal-socket '14 and at the other end in an openjournal 15, in which journal it may be retained by means of a spring 16,as shown, or this removability of said roller may be accomplished inother specilic manners, as will be obvious to the skilled mechanic.I/Vhen the tension roller 12 is made removable, as described, theperforated sheet of music may be partially unwound from the music-roll,passed over the tension-roller 1l between the guides 5, and attached tothe take-up roll in any usual manner, and then the tension-roller 12introduced into its journal-bearings, the then relative arrangement ofthe elements being shown in Fig. I of the drawings, with the guidesdirecting the movement of the music-sheet and the tension-rollersimparting the requisite tension thereto and maintaining the sheet in asmooth unwrinkled condition and in proper close cooperative relation tothe tracker-board in its travel thereover. During the rewinding of thesheet upon the music-roll, which is accomplished with rapidity, thetensioning function is not needed, and therefore during this operationthe roller 12 may be removed.

Having thus described the invention, what I claim is- 1. The combinationwith a music-roll, a takeup roll and a tracker-board, of slidesinterposed between the music-roll and the trackerboard and arranged tobe adjusted upon the latter, guides operatively connected to saidslides, and a rod having screw-threaded engagement with said slides andguides for adjusting the same to and from each other, substantially asdescribed.

2. rfhe combination with amusic-roll,atake up roll and a tracker-board,of slides interposed between said music-roll and the trackerboard andarranged to slide upon the latter, music-sheet guides connected to saidslides, means for adjusting said slides and guides to and from eachother and means for maintaining the same in alinement, substantially asdescribed.

3. The combination with a music-roll,a takeup roll and a tracker-board,of slides interposed between the music-roll and the trackerboard andarranged to slide upon the latter, music-sheet guides operativelyconnected to said slides, screw-threaded nuts connected to said slides,alinement-lugs for said guides and a screw-threaded rod for engagementwith the screw-threaded nuts and the alining lugs, substantially asdescribed.

11. The combination with a music-roll,a takeup roll and a tracker-board, of adjustable guideplates interposed between the musicroll andthe tracker-board, and a music-sheet tension device along which saidguides are adjusted, substantially as described.

5. The combination with a music-rolLatakeup roll and a tracker-board, ofguide-plates interposed between the music roll and the trackerboard, amusic -sheet tension -roll passing through said guides and journaled instandards, and means for adjusting said guides to and from each other,substantially as described.

6. The combination with amusic-roll,a takeup roll and a tracker-board,of musicsheet tension-rolls interposed between the musicroll and thetracker-board and mounted in standards, one of said rolls beingremovable, and guide plates interposed between the music-roll andtracker-board, substantially as described.

7. The combination with amusic-roll,a takeup roll and a tracker board,of musicsheet tension-rolls interposed between the musicroll and thetracker-board and mounted in standards, one of said rolls beingremovable, and adjustable guide-plates interposed between the music-rolland tracker-board, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing' witnesses.
